Introduction

Connect Tech’s COM Express Carrier Boards are small feature rich, super flexible carrier boards that

integrate with any industry standard type II COM Express module. These bus-independent carrier boards

offer easy connection to SATA HDD, USB, Ethernet, HDMI Video, LVDS Video, VGA video, RS-232 and

RS485 serial.

Connect Tech’s COM Express carrier boards are ideal for compact and high performance computing

applications in mobile entertainment, kiosks, digital signage, automation, ROVs and gaming applications.

ESD Warning

Electronic components and circuits are sensitive to

ElectroStatic Discharge (ESD). When handling any circuit

board assemblies including Connect Tech COM Express carrier

assemblies, it is recommended that ESD safety precautions be

observed. ESD safe best practices include, but are not limited

to:

Leaving circuit boards in their antistatic packaging

until they are ready to be installed.

Using a grounded wrist strap when handling circuit

boards, at a minimum you should touch a grounded

metal object to dissipate any static charge that may be

present on you.

Only handling circuit boards in ESD safe areas, which

may include ESD floor and table mats, wrist strap

stations and ESD safe lab coats.

Avoiding handling circuit boards in carpeted areas.

Try to handle the board by the edges, avoiding contact

with components.

* J10 Provides the CS4207 Audio Codec with the Sense input:

The Sense input is used by Audio Codecs to detect the presence of an audio plug being installed into an audio jack,

via a switch inside the jack. The Audio jacks on the COM Express carrier do NOT have this switch, so we have

provided these jumpers to mimic that function.

Not all operating systems require this sense input to be satisfied, for example audio under Ubuntu 10.04 LTS will

function fine without the Jumpers, however audio under Windows XP will not.

Standard Serial

Description

The CCG0xx series of COM Express adapters features four serials ports. Port1 and Port2 are standard RS232 and

Port3 and Port4 are RS485. The SMSC SCH3114 Super I/O chip is used to facilitate the serial I/O. This chip requires

both an LPC bus connection from the module and BIOS support to operate. Ask your module vendor or examine

your module documentation to determine of BIOS support is available for the SCH3114.

The pinouts are as followss

RS485 Control Jumpers

The RS485 Control Jumpers are used for implementing the following RS485 modes of operations:

½ Duplex Multidrop

Full Duplex Multidrop

The UART RTS signal is used along with the J11 jumpers to facilitate these modes.

B Power Good when using +12V Supply

C Reset input to module

D Power Button input to module

E External Battery

F No Connect

Notes:

Position A: If ATX power supplies are used, this signal can be used to override the PS_ON signal from the

Carrier board and simply force the PS_ON signal to 0V. The ATX supply should switch on as soon as it is

powered.

Position B: Used when operating with a +12V power input. This jumper will route 5V to the POWER_OK

pin on the COM Express module.

Position C: SYSTEM RESET input to the COM Express Module

Position D: POWER_BUTTON input to the COM Express Module

Position E: An External Battery could be wired here if the one on the carrier not needed.

Typical Hardware Installation for +12V power input

1. Ensure all external system power supplies are off.

2. Install the COM Express module into P1. Be sure to follow the manufacturer’s direction for proper

heatsink/heatspreader installation and any other cooling instructions from the manufacturer.

3. Verify all jumper settings from the relevant sections, paying special attention the power selection jumpers.

Some typical settings are outlined below.

Jumper Function Position

J4 Power Good +12V Power 3-4

J12 +5V To standby +5V to middle

4. Install the necessary cables for the application. At a minimum, this would include:

a) +12V Power cable to P7

b) Video display cable VGA, and/or HDMI.

c) Keyboard and mouse via USB

d) SATA Power and Signal to SATA HDD

For the relevant cables, see the Cables & Interconnect section of this manual

5. Connect the power cable to power supply

6. Switch on the power supply. DO NOT power up your COM Express system by plugging in live power.

Software Installation & Configuration In general, always refer to the COM Express module’s manual for proper installation of software drivers and

configuration software; as well as for appropriate BIOS settings.

The following sections provides some specific notes and hints for successful module integration
